So....Usain Bolt decides that he's trans, and become Usaina. Has the hormone therapy, the op, changes his name legally, and is now only to be referred to as a woman.
He/She/They then enters all the women's 100m sprint. The women's WR was set in 1988, never been broken since at 10.49s, the men's WR was set in 2009 by Usain Bolt at 9.58s.
Is it realistic that when Usaina Bolt absolutely annihilates the 1988 Women's WR, that people just shrug their shoulders and say "well the record had to go sometime"?
If we are to develop a "3rd strand" of sex, then have a Trans Olympics.
